CircularSector Command
Syntax: CircularSector[point C, point A, point B]
Action: Creates the circular sector with center C between two points A and B, using CA as the radius, and also a number that is equal to the area of the sector.
Example: S = CircularSector[(0,0), (1,0), A] - creates the clockwise circular sector of the unit circle defined by the position of point A relative to the x-axis, and the variable S contains the area of the sector.
Notes
- Point B is used to define the angle; it will not in general be part of the sector.
- a unique name will be given to the sector's area if you do not specify one.
- Points explicitly specified will not be created.
